What to expect in WSO2 CEP 4.0

WSO2 Complex Event Processor 4.0 is released! A long waited CEP release from WSO2. This is a major break through among current CEP products.

Here are some notable features it has introduced :

Scale and Performance 

1. Support for distributed processing with Apache Storm - WSO2 CEP runs Siddhi CEP on Apache Storm in a distributed mode while providing an SQL like Siddhi Query Language to define queries on Storm. 
2. Faster CEP engine with WSO2 Siddhi 3.0 - With LMAX Disruptor and improved memory management, Siddhi was able to run even faster than its predecessors doing ~ 4M Events/Sec
3. HA Support - Supporting Hot-Worm High Availability with zero downtime
4. More effective native thrift/binary transports 

Usability 

1. Realtime Dashboard support - Support for gadget generation wizard and customisable realtime dashboard
2. Easy to use management console for business users - Ability to tweak queries with a form based UI without knowing the implementation and complexities of SiddhiQL, Storm and  Java 
3. Event simulation capability - Try sending events easily 
4. Siddhi query try-it - Try writing queries 
5. Event flow visualisation - See how you the event flow pipeline will look like

Enhancements  

1. New protocols introduced such as MQTT, Kafka, Websocket - Support for many new and improved event receiver and publisher capabilities
2. Enhanced query language with more extensions -  Such as Function, Stream Processor, Window and Aggregate Function Processor
3. Support for machine learning via ml, pmml (Predictive Model Markup Language) extensions - To run machine learning model on realtime
4. Support for Natural Language processing via nlp (Natural Language Processing) extension - Supported via Stanford NLP
5. Geo processing capabilities via geo extension and Geo Dashboard - Dashboard having the capability to monitor and apply queries on geo spaces. 
6. Support for scripting using JavaScript, Scala and R - Can use scripts to write CEP logic!

This release not only overcomes the scaling bottleneck of previous WSO2 CEP versions, but it also provides a seamless query language that allows uses to run the same queries both on single node and on distributed environment, making WSO2 CEP 4.0 as a unique product in the market.
